Pediatric emergency physicians are experienced in the diagnosis and treatment of all types of emergencies in infants, children, teens, and young adults. They usually treat the following types of emergencies:
Solar irradiance. It's reasonable to assume that changes in the sun's energy output would cause the climate to change, since the sun is the fundamental source of energy that drives our climate system. Indeed, studies show that solar variability has played a role in past climate changes.
The external climate forcing processes and the internal climate forcing processes except the man-made processes are grouped together as natural causes of climate change while the man-made processes are the anthropogenic or human causes of climate change. The natural causes are believed to even out eventually and are not considered to be responsible for climate change.
